The, frame by which the index elements are held consists preferahlyof a horror tray 1. having oppositely disposed channels 2., near its bottom.

A. aeriea of transverse wire rods 3 extend between the channels 2, with their ends loosely held th e n so that they Ina slide lengthwise of the channels.

2. of npatanding, composite index elements are attached to the rods 3, and swing on the rods hinge members. Each index element. as! herein shown, comprises a eard holder 4, preferably of transparent eheet celluloid, having a fold or bent-over l'EIQ-UElWT at its bottom edge through which the rod extends and a folded lip (5, consth tilting card engnigin emeans at thetop. A card 7 is hcid at its upper edge by the card engaging lip (i and in of sul etantially the same. hoig'l'it as the card holder so that its hottom edge which is Wholly unattached to the card holder, may rest upon the bottom of the tray 1, which prevents the top edge of the card fren'i slipping out from iinder tho i an embodiment of the 1n- Specification of Letters Yatent.

Each card may be provided with an index tab 8 projecting; from its upper edge, and the fold of lip (i is in that event provided with a slot or a 'iertnre 9 through which the tab projects; the tabs and the correapomling slots of the several index elements ma be arranged in rows from front to rear, or in diagonal or steppec. positions. or otherwise as desired. The tabs may also he of an usual or desired construction. thone herein SllO'WD. being formed of a folded piece o'i' transparent sheet celluloid cemented to the .niargin of the card, forming a sheath or pocket into which a slip may he inserted. bearing the desired index characters.

The matter to he recorded in the index may he inscribed upon the cards 7. which being, readiiv rcnidvahle, may be replaced as often as necessary. Gr. if the nature of the records involves a too rapid nainn up of space or a too frequent discarding or changing of the recorc I a saving can be effected by retaining the cards Y as a pernmnent. part of the equipment. and cnzering the records (in sheets of paper 10 folded o-;er the top edge of the. card. and provided with a slit 11. through which the tab 8 projects.
